You combine everything but the alcohol and bring to a boil, then simmer for a minute. Let cool to room temperature and add the alcohol, if you don't that alcohol is gonna go right up in flames, its super volatile.

Anywhoo, so you take out the cinnamon sticks, throw it in some sanitized mason jars and put it in a dark cupboard, three weeks minimum before you open it. It will last for up to a year this way. Looking forward to trying it!
